After further Goltecting:| in 1 Calocnia: apparently always in 
the vicinity of Monterey, Coulter returned to Europe by way 
of Mexico, in the year 1834, bringing with him his collection 
of over 50,000 specimens, probably representing between 
1,500 and 2,000 species, besides a collection of nearly 1,000 
woods, botanical manuscripts, journal, and additional mate- 
tials for a personal narrative. All these manuscripts were in 
some unaccountable way lost in transport between London 
and Dublin. Suffering from this loss, and broken in health 
from the hardships of his travels, he devoted himself there- 
after quietly and unremittingly to the arrangement of his 
herbarium, which, with its total of about 150,000 specimens, 
became the property of Trinity College, he himself being La 
pointed keeper, or curator. At the time of his death, 
1843, he had completed the arrangement of the European 
plants and had begun on his American collections. 
The collections of Cactacee sent to De Candolle seem to 
have contained the only ones of Coulter’s plants that reached 
an avenue of publication previous to his death, with the ex- 
ception of five new Californian pines described in the 
paper by David Don, and the Cupressus coultert of 
Forbes.2° But Professor W. H. Harvey, upon his ap- 
pointment as Coulter's’ successor, in 1844,?! proceeded with 
the arrangement of the Californian and Mexican plants, 22 is- 
sued three short papers?? on them, and, apparently in the 
years 1846 to 1848, distributed the greater part of the dupli- 
Cates, the first set going to Kew and others to Dr. Asa Gray 
and Dr. John Torrey in America. The specimens were sent 
out under more than 1,700 numbers, unfortunately arranged 
systematically instead of ibe int
